When once asked to describe Arsenal's playing style, Jurgen Klopp stated: “It's like an orchestra, a silent song. But I like heavy metal.”

And while Liverpool still aren't quite thrashing out the right tune, both they and their supporters are at least beginning to rediscover their voice at Anfield.

Klopp will be left nursing a banging head attempting to fathom a raucous, crazy night that ended with his players once again saluting the Kop after a dramatic last-minute equaliser.

If the unified response to Divock Origi's late strike against West Bromwich Albion had the air of a well-intended stunt, the manner in which the Reds boss leapt into the snowy night air to celebrate substitute Joe Allen's leveller was purely instinctive.

Delight, yes. But relief also, given the manner in which the Reds had seemingly thrown away the opportunity to halt Arsenal's growing title momentum.

Twice given a first-half lead by the impressive Roberto Firmino – the Brazilian's first Anfield goals since his £29million summer move from Hoffenheim – Liverpool offered gifts to Aaron Ramsey and Olivier Giroud before the latter's strike sent the Reds to the brink of a fourth defeat in seven Premier League games.

The home fans, to their credit, never gave up. Nor did the players, despite the sight of loan centre-back signing Steven Caulker being thrown on up front late on for his debut highlighting how Liverpool had struggled in the closing stages to fashion genuine chances.

For former Reds boss Rafael Benitez, watching on from the stands, this had many of the hallmarks of the kamikaze 4-4 draw between the sides in 2009.

That arguably cost Liverpool the title that year. This result, though, has given tantalising hope the Reds still have a chance of Champions League qualification, continuing their impressive record against leading teams this season.

But while there can be no questioning their character – there's certainly no reason for any home fans to leave Anfield early these days – defensively there remains much room for improvement..

Yes, the availability of Mamadou Sakho and Kolo Toure meant at least Klopp could call on some senior centre-backs.

Sakho, though, endured a difficult evening, while the entire defence wasn't helped by Simon Mignolet marking news of an imminent new contract by reprising the jittery, indecisive displays of last season.

And then there was the defending at set-pieces. Unlike most opponents, Arsenal aren't renowed for their prowess with the dead ball. For Liverpool's panicky backline, though, it was as if Wimbledon of the 1980s were back in town.

Thank goodness, then, the Reds were, in the first half at least, much more lively going forward.

With skipper Jordan Henderson back after missing the last three games with a recurrence of his long-standing heel problem, Klopp reverted to the 'false nine' formation that had served so well in those impressive wins at Manchester City and Chelsea.

In terms of bolstering Liverpool's attacking threat, the effect was immediate as Klopp's side – with just 22 goals in 20 previous Premier League games – produced a vibrant attacking performance, prompted by Firmino – his best game for the club – and the busy James Milner and Adam Lallana.

It had started so well. Liverpool signalled their intent from the first whistle, immediately wresting the initiative and were ahead on 10 minutes with wouldn't be the last goal of the evening to come from a corner.

After Arsenal failed to properly clear their lines, the ball fell to Emre Can outside the area whose shot was parried out by Petr Cech straight to Firmino 12 yards out, the Brazilian firing firmly through the legs of Laurent Koscielny and into the goal.

A deserved reward, it was surrendered cheaply four minutes later. With Arsenal's first real attack, Joel Campbell slipped Ramsey in behind Sakho – dazed by a clash of heads moments earlier with Giroud – and the Arsenal man's low shot beat Mignolet too easily at the goalkeeper's near post.

Six minutes later, though, and Liverpool were back ahead in spectacular fashion, the Reds keeping the ball alive on the edge of the area before Milner rolled the ball across to Firmino to curl a brilliant effort into the top corner from 22 yards.

It didn't last long, Arsenal level once again on 25 minutes. The warning was there when Ramsey beat Mignolet to reach a ball over the top first only for his lob to be cleared off the line by Sakho.

But Liverpool failed miserably to deal with Ramsey's resultant near-post corner delivery from the left, Giroud claiming the slightest of touches as the ball evaded Mignolet.

And the Frenchman should have given Arsenal the lead shortly afterwards as, with the Liverpool defence again all over the place, he somehow diverted Theo Walcott's low cross back towards the beaten Mignolet rather than into an empty net.

Firmino struck the bar in first-half injury time and, after the restart, saw his cross wastefully volleyed over by Alberto Moreno.

And that miss proved costly as Arsenal went ahead for the first time on 55 minutes, the ball deflected into the path of Giroud who turned, evaded the falling Toure and shot into the bottom corner.

Liverpool, with Caulker introduced to play up front alongside fellow substitute Christian Benteke in the closing moments, struggled to muster a response until Allen popped up at the death, beating Hector Bellerin to Benteke's knockdown from a Henderson long ball to volley beyond Cech.

This was the first of four home games over the next fortnight that will go a long way to shaping the remainder of Liverpool's season.

Fortress Anfield is some way from being rebuilt. But, with Manchester United up next, the foundations are slowly being put in place.
